Screenshotting from a Strategy

[NinjaTrader_ChelseaB]

Hello NinjaCustomer,

Its taking a screenshot of the active tab of the chart the script is applied to.

[NinjaCustomer]

how could I check that the active tab is the same chart as the strategy is running on? I want to make my code only take a screenshot if the correct tab is active.

Hello NinjaCustomer,

Below is a link to a few examples that detect if current tab is the tab the indicator is applied to.

ok, just one last small question...

how does a Strategy that is not attached to a chart work? does it have some invisible chart? I mean, Strategy code that interacts with Chart objects like getting the Chart variable or drawing objects on the Chart I assume is perfectly safe to run in a Strategy that is created in the Strategies tab and is not attached to any specific chart in the workspace, correct?

Hello NinjaCustomer,

If added to the Strategies tab of the Control Center directly or when backtested, the ChartControl will be null. The primary data series is selected in the strategy parameters for the Strategy Analyzer and Strategies tab of the Control Center.

If the ChartControl is null, those actions won't happen.

Below is a link to the Strategy Builder 301 course which demonstrates enabling a strategy on the Strategies tab of the Control Center.

my OnRender() is not being called. I put a Print statement in there and can't see it in the output. I have a ForceRefresh() call also but the event doesn't get called.

I simply placed the OnRender event in Strategy.. is that correct? or do I need to somehow attach it to ChartControl?

[NinjaCustomer]

I added the base render call and for some reason it works now.. very strange that the print statement wouldn't work without it

Hello NinjaCustomer,

The print is in the same OnRender() as the base call?

If was another script it might make sense...

Not sure on this one.

Hello NinjaCustomer,

I have received tracking ID# SFT-3955 for this request for a method for saving screenshots.

Please note it is up to the NinjaTrader Development to decide if or when a request will be implemented.

We appreciate your feedback.

[NinjaCustomer]

if they do actually implement it, do you think it will be able to save charts on tabs that are not active?

[NinjaTrader_ChelseaB]

Hello NinjaCustomer,

This was not requested and I will not be able to speculate.

I will submit a request to take screenshots of inactive tabs. Once I have a tracking ID for this request I will post in this thread for future reference.
